• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((thanh trung) OR (thanh tung)) cua khong cang dan ((ca cau) OR (cua cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((thanh trung) or (thanh tung)) cua khong cang dan ((ca cau) OR (cua cau))".
